» COMMON QUESTIONS
What network teams ask first.
Will it put load on my network?
No. FLOWCUTTER is passive — it reads flow data your routers already export, or captures via SPAN/TAP with the Probe. Nothing sits in the traffic path.
Do I need to change my network architecture?
Which devices are supported?
On-premise or cloud?
Who deploys it?
Our engineers do it remotely with your team, typically in a single session.
» 30 days. Your infrastructure. Your real traffic.
